pursuit of a more perfect union, of a grandfather who marched across europe, of a friend who bought it -- fought in vietnam, a sister who fought in iraq, stories of generations of americans who left home at barely more than boys and girls and became men and women and return home heroes. when these americans who have dedicated themselves to defending their lives to defending it -- defending this country, many settled on a life of service, choosing to make their entire lives a tour of duty. many chose to live a quiet life, trading one uniform for another -- doctor, engineer, a teacher, mother, father. they bought homes, raised families, built businesses. they built the greatest middle class the world has ever known. some put away their medals, state humble about their service and move on.
